New Lepidoptera collected by Mr. T. A. Barns 143 



abdomen concolorous with wings ; abdomen with paired (subconfluent) 

 dark spots. Legs pale ochreous-grey, more or less dark-spotted on 

 upper and inner sides. 



Fore wing glossy-whitish, with light grey-brown suffusions ; costal 

 margin as far as postmedian (with the exception of narrow pale 

 median space) dark-spotted ; markings grey-brown ; basal patch slightly 

 darkened, bounded by a strong, nearly vertical wavy dark line ; median 

 band of moderate width, bounded by slightly crenulate wavy dark lines, 

 the antemedian slightly and regularly excurved throughout, the post- 

 median slightly sinuous, straightest between the radials, very gently 

 excurved between M 2 and SM 2 , with no marked lobe in middle ; three 

 faint lines of dark irroration indicated between basal patch and median 

 line ; two lines proximally, and apparently three distally indicated on 

 the median band, connected and obscured by dark shading ; only a 

 small patch around the minute celldot (reaching costa) and narrow 

 interrupted streak from this to hind margin remaining pale ; a narrow 

 white band (clearest proximally) beyond the postmedian, intersected by 

 a very faint dark line ; distal area irregularly suffused, bounded (at least 

 proximally) by an ill- defined and irregular dark line ; subterminal line 

 lunulate-dentate, only developed anteriorly, where it is filled in 

 proximally with ill-defined dark spots ; a (not very conspicuous) white 

 dash at apex, the terminal clouding darkest behind this ; terminal line 

 indicated by paired dots at the veins ; fringe nearly unicolorous. 



Hind wing glossy ; dirty white, unmarked, except for some slight 

 spots at abdominal margin. 



Fore wing beneath slightly suffused from base to postmedian, 

 costally darker, with irregular irroration from base to postmedian and 

 (more weakly) near termen ; a celldot and postmedian line indicated, 

 the latter strongest between M 1 and abdominal margin. 



Tanganyika : Niragongo, Kivu, October, 1919. (T. A. Barns.) 



A nearly unmarked specimen taken at the same time and place (at 

 4000 m.) is perhaps a form of the same species, perhaps a near ally. 

 Rather larger and rounder-winged, the celldot of fore wing less minute, 

 the postmedian line apparently rather more curved. Without more 

 material I do not venture to name it or pronounce definitely on its 

 status. Both specimens show the palpal and antennal structures of 

 Xanthorhoe conchata Warr. and bear (except for the biangulate disco- 

 cellulars of the hind wing) a good deal of resemblance to that species; 

 smaller, fore wing and underside paler (not reddish), wings rather 

 shorter ; the pale colour is almost that of Epirrhoe cancellata Warr.
